Activewear

Activewear That Earns Its Place in a Real Wardrobe.

Activewear has a credibility problem. Much of it is designed for the gym selfie rather than the workout, for the aesthetic rather than the activity. At Sostter, the activewear brands we carry are chosen for a single, non-negotiable reason: they are genuinely good at what they are supposed to do. Performance clothing that moves properly, lasts properly, and looks good as a byproduct of being well made rather than as the whole point.

From Kymira's infrared performance wear — used by professional athletes across cycling, running and recovery — to Latched's award-winning maternity and nursing activewear that supports mothers through pregnancy, postpartum and beyond, and Alana Athletica's considered sustainable sportswear, every brand in this collection brings genuine purpose to what it makes. Sustainable materials, ethical production, and clothing built to be worn hard and washed often — not admired from a distance.
